Benefits of technology

The present invention describes a cooling plate for battery cells that improves cooling performance compared to prior art. The cooling plate has flow ducts with perturbing contours that increase turbulence in the coolant, minimizing temperature gradients. The cooling plate also has a first port for supplying the coolant and a second port for draining or outflowing the coolant, making it reliable and compact. The technical effects of this invention include improved cooling performance, reduced temperature gradients, and reliable and compact design.

Problems solved by technology

Such cooling plates have the drawback that a reliable temperature control of the traction battery cells is not always possible.

Embodiment Construction

[0032]In the various variant embodiments, the same parts are given the same reference numbers.

[0033]FIG. 1 shows in a perspective view one embodiment of a cooling plate 10 according to the invention for the temperature control of at least one battery cell.

[0034]The cooling plate 10 comprises a frame 12. The frame in the exemplary embodiment shown in FIG. 1 is made of plastic. The cooling plate 10 comprises a flexibly configured cover 14. The frame 12 comprises flow ducts 16. The flow ducts 16 are covered or closed off by the flexibly configured cover 14. In particular, the flow ducts 16 are closed off by the flexibly configured cover 14 from the outer surroundings.

[0035]FIG. 2 shows a perspective view of the frame 12 without the flexibly configured cover 14 in order to reveal the flow ducts 16. The flow ducts 16 are oriented each time along a longitudinal direction 18. In the exemplary embodiment shown in FIG. 2, the frame 12 comprises for example ten flow ducts 16. The flow ducts 1...

Abstract

A cooling plate (10) for the temperature control of at least one battery cell, especially for a traction battery, comprising a frame (12) with flow ducts (16) designed for the flowing of a coolant through them and a flexibly configured cover (14), which bounds the flow ducts (16) in fluid-tight manner and is provided for the thermal contacting of the at least one battery cell. It is proposed that the flow ducts (16) comprise at least one perturbing contour (28), which is provided to increase the turbulence in the coolant flowing through the flow ducts (16).

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a cooling plate for the temperature control of at least one battery cell. Furthermore, the invention also relates to a battery system with such a cooling plate.[0002]Cooling plates are known from EP0516280A1 for the temperature control of traction battery cells, having flow ducts covered by a flexible cover for the thermal contacting of the traction battery. Such cooling plates have the drawback that a reliable temperature control of the traction battery cells is not always possible.SUMMARY OF THE INVENTION[0003]The present invention describes a cooling plate for the temperature control of at least one battery cell, especially for a traction battery. The cooling plate comprises a frame with flow ducts designed for the flowing of a coolant through them and a flexibly configured cover. The flexibly configured cover bounds the flow ducts in fluid-tight manner and is provided for the thermal contacting of the at least one battery...
